Better Auth Cosmos DB Adapter

This project provides a custom adapter for better-auth that integrates with Azure Cosmos DB. It allows for seamless interaction with the required tables: User, Session, Account, and VerificationToken.

Installation

To install the adapter, run the following command:

npm install better-auth-cosmos

Usage

To use the adapter, import it into your application and configure it with your Azure Cosmos DB connection string and database name.

import { buildCosmosAdapter } from 'better-auth-cosmos';

export const adapter = buildCosmosAdapter({
    adapterId: 'cosmos-adapter',
    adapterName: 'Cosmos Adapter',
    dbCredentials: {
        connectionString: process.env.COSMOS_DB!
    },
    dbName: process.env.COSMOS_DB_NAME || 'better-auth',
    debugLogs: true,
    usePlural: false,
});

API

I am not supporting custom CosmosClient objects and instead initializing through config. Since this adapter is specific to the better-auth implementation, we really don't care about exposing functionality and can leave the abstraction as-is.

import { betterAuth } from "better-auth";
import { cosmosAdapter } from "../my/code";
 
export const auth = betterAuth({
  database: cosmosAdapter({ ...options })),
});

Contributing

Contributions are welcome! Please open an issue or submit a pull request for any improvements or bug fixes. Run the tests with an instance of cosmos to verify changes.
